As project founder Professor Dan Zaslavsky explains, the Energy Tower works on the basic principle of convection: hot air rises and cold air falls. The 3,000-foot tall tower, with a diameter of 1200 feet, would take advantage of the heavy falling weight of cold air.

Bullshit science in this article.

"Solar updraft towers" http://en.wikipedia.org/wiki/Solar_updraft_tower do exist though, but they work in the reverse direction to the ones in this article (air in at bottom, heated by greenhouse, rises out the top). They're kinda snazzy, but not the wonder device proposed here.

I have to laugh at all the "fail" comments. That stupid term is so over-used its pathetic.
I love how so many seem to have been able to tell exactly how this "device" works based on a 10, 000ft over-view article. Tons of technical detail there eh?

Morons!
Do some real research before coming to ridiculous conclusions based on nothing but your arrogance.

Epic Fail. Nowhere does this device take into account the massive amount of energy that would it would take to to lift the cold water up that high. Now if they're able to put it over the Mediterranean where all water evaporates and somehow turn a turbine that way it might work. This one does not.

From the page: "Because it relies on the sun for hot air, the Energy Tower is considered a type of solar power. Due to the original hot air required at the top, the concept would work best in hot, dry climates. The team has identified regions in about 40 countries where towers could work, including in the Middle East, Australia, North Africa, California, and Mexico.

The researchers also predict that the project would be cheap - electricity generated from this method would cost just 2.5 cents per kilowatt-hour, which is less than a third of the cost of electricity in Israel today. It's also cheaper than solar, hydro-electric, and wind power. "

This might work, but salt water will corrode the tower, and it's hard to find a part of the world that has enough available land, lots of sunlight and ready access to water. Check Wikipedia for more... and while you are at it, read about something that might work even better - the solar updraft tower,/a>.
